Which of the following are anions? Check all that apply. a
Fluorine
b
Phosphorus
c
Lithium
d
Oxygen
e
Sodium
f
Lead

The answers are A, B, and D because they gain electrons, meaning the will become a negatively charged ion.

For F, I’m pretty sure it can be either or because it can either lose 4 electrons or gain 4 electrons. So I recommend looking it up.

Hope this helps :)

And a) oxygen i believe
